Keeping Volume Fraction of Fluid in Reconstructing Moving-interfaces of VOF on Rectangular Meshes
Ruyun Wang · Jisuan wuli · 2008
A moving interface reconstructing algorithm keeping volumed fraction of fluid in the volume of fluids(VOF) method is presented.The moving interface is approximated by a diagonal line of a grid,and two diagonal lines located in adjacent grids intersect on a public side.By keeping constant volume fraction of fluid in each grid,nonlinear equations are built on boundary grids.Location of intersecting points of moving-interfaces with grid sides are decided by solving equations.The shape of moving-interfaces is reconstructed.The method simulates accurately moving interfaces with fewer cusps.Its availability and efficiency are demonstrated.
